AI Technical Summary

Benefits of technology

This approach reduces current consumption and enhances performance by accurately calibrating and managing leakage power, optimizing the sleep mode activation of IC functional blocks based on power and latency requirements.

Problems solved by technology

Circuits that remain active, although not presently needed, may increase power consumption and / or raise an operating temperature which could have adverse effects.
Moreover, many mobile electronic devices operate on batteries or other limited power sources.

Abstract

An integrated circuit and a method for efficiently operating integrated circuit devices. The integrated circuit includes an input that is configured to receive a first current which is representative of a leakage current drawn by leakage in a portion of the integrated circuit. The integrated circuit includes a leakage calibrator that is configured to compare the first current to a current required to perform a switching operation and output a value indicative of the leakage.

Description

CROSS REFERENCE TO PRIOR APPLICATIONS[0001]The present application is a continuation of U.S. patent application Ser. No. 12 / 124,812 filed May 21, 2008, which claims priority to U.S. Provisional Patent Application Ser. No. 60 / 939,196, filed May 21, 2007, entitled “Leakage Calibration,” each of which is hereby incorporated by reference in its entirety.BACKGROUND[0002]1. Field[0003]This disclosure relates to a system and a method for efficiently operating integrated circuit devices. More specifically, this disclosure relates to a method and a system for calibrating leakage currents in integrated circuit devices.[0004]2. Related Art[0005]Power consumption management is a concern in many electronic devices. Circuits that remain active, although not presently needed, may increase power consumption and / or raise an operating temperature which could have adverse effects. Moreover, many mobile electronic devices operate on batteries or other limited power sources. Some mobile electronic devic...
